Linda, what matters is that you don't quit. Make up your mind to stay with it. Read "The BECK DIET SOLUTION" by Judith Beck, PhD as she teaches how to THINK like a THIN person. We have a Team here for support. I got her book at the library. It is a six week course.
I found Roby Mitchell, M.D. to be of great help. His web site is at www.drfitt.com
He had advanced prostrate cancer and treated himself with diet and exercise and I found him when my then 24 yos had Testicular Cancer. Dr. Mitchell is 54 and a very interesting man. He graduated from Texas Tech Medical School and has a PhD as well.
